Benefits of technology
[0005]It is an object of the present invention to provide a mortise door lock that is easy, and cost effective to manufacture.
[0006]It is an object of the present invention to provide a mortise lock that is easy to install.
[0007]It is an object of the present invention to provide an improved mortise lock which offers added security and performance over other two-point mortise locking systems.
[0009]It is still another object of the present invention to provide an improved mortise lock that will not require a large bored cavity fro installation.
Problems solved by technology
The installation of a mortise latch cannot generally be undertaken by the average homeowner since it is labor intensive and requires a working knowledge of basic woodworking tools and methods.
Many installation specialists use a mortising jig which makes precise cutting of the pocket a simple operation, but the subsequent installation of the external trim can still prove problematic if the installer is inexperienced.

The two-point mortise latch of the present invention includes, a central actuator having teeth that are meshed with the teeth of a gear wheel, wherein the gear wheel and the central actuator are pivotally connected to at least one hook, via the hook arm. Wherein the top and bottom surfaces of the hooks have guide protrusions that are set in a guide their respective guide areas. The hooks are designed to contact the bottom interior surface of the keeper housing when latched. The central actuator and gear are meshed together via teeth. In addition, the central actuator and gear wheel are biased with springs so as to facilitate opening and closing of the door latch. The components of the present invention are retained inside of the housing, which is set inside the lock stile of a door.
Description
FILED OF THE INVENTION [0001]The present invention relates to sliding door locks in particular sliding door locks, which implement a two point mortise.BACKGROUND OF THE INVENTION [0002]Mortise locks and latches have been implemented for over a century. Generally, mortise locks and latches require a rectangular hole in the door edge for installation, and for all intensive purposes are identical, the only difference is that a mortise lock actually locks whereas a mortise latch only latches. The present invention is compatible with either type of mortise door system. For the purposes of brevity a mortise latch will be described only, keeping in mind that the present invention may be used with a mortise lock just as easy.[0003]A mortise latch (mortice lock in British English) is one that requires a pocket—the mortise—to be cut into the door or piece of furniture into which the lock is to be fitted. In most parts of the world, mortise latches are generally found on older buildings constr...
